Backward-curved motorised impellers develop pressure within the envelope of the impeller and do not, therefore, rely on a scroll housing for this purpose. They are relatively low cost and can be simply and cheaply housed.
Air is drawn through a radius inlet ring, which minimises pressure losses and air leakage, and is discharged at 90° to the inlet axis. The impeller has a ‘non-overloading’ characteristic in that it draws maximum power near the centre of its pressure/volume flow curve.
Low-cost speed control is possible by supply voltage variation, either by an electronic (triac) method or by a transformer.
